Error with cookie-value when adding a new Spring Session

Question

In my Spring Boot 1.4 based application I use Spring Session to store session data in the database with JDBC.

This works fine

Answer 1

CookieProcessor is a new configuration element, introduced in Tomcat 8.0.15. The CookieProcessor element allows different cookie parsing configuration in each web application, or globally in the default conf/context.xml file.

According to official docs at Apache Tomcat 8 Configuration Reference Version 8.0.47 :

The standard implementation of CookieProcessor is: org.apache.tomcat.util.http.LegacyCookieProcessor. Note that it is anticipated that this will change to org.apache.tomcat.util.http.Rfc6265CookieProcessor in a future Tomcat 8 release.

Later..

According to official docs at Apache Tomcat 8 Configuration Reference Version 8.5.23:

The standard implementation of CookieProcessor is org.apache.tomcat.util.http.Rfc6265CookieProcessor.

To resolve this issue: add this line in conf/context.xml at location %CATALINA_HOME% (i.e. C:\apache-tomcat-8.5.20\conf\context.xml in my case):

This is how it looks like after adding:

    WEB-INF/web.xml
    ${catalina.base}/conf/web.xml
